BEARING MECHANISIVI.

Specification of Letters Patent.

Patented Nov. 18, 1.913.

T 0 all whom t may conc-cra Be it known that I, ROBERT S. BROWN, acitizen of the United States, residing at New Britain, in the county ofI-Iartford and State of Connecticut, have invented certain new anduseful Improvements in Bearing Mechanism, of which the following is aspecification.

This invention relates to bearing mechanism, among the objects of theinvention being the provision of a device of the character noted havingmeans for rigidly and substantially supporting one or more spindles orshafts and for effectually resisting and distributing' the thrusts ofthe same.

The invention possesses other features of novelty and advantage whichwith the foregoing will be described at length in the followingdescription wherein I will set forth in detail that one of the severalforms of embodiment of the invention which I have selected forillustration in the drawings accompanying and forming part of the same,this disclosure being to enable those skilled in the art to practice theinvention. I do not limit myself to such disclosure; I may departtherefrom in several respects within the scope of the invention definedby the claim following said description.

Referring to said drawings: Figure 1 is a side elevation of bearingmechanism involving my invention. Fig. 2 is afront elevation of thesame, and, Fig. 3 is a transverse section on the line 3-3 of Fig. I.

Like characters refer to like parts throughout the several views.

lVhile I do not limit myself to the embodiment of my improvements in anyparticular. kind of machine, they are of especial utility whenassociated with or forming part of a multiple-spindle automaticturret-machine such for example as shown in Letters Patent No. 874,035granted December 17, 1907 to George G. Prentice, to which reference maybe had and which is partly illustrated in the drawings. The machineshown comprises in its organization a bed 5 at the head end of which aredisposed at least two rigid supports or uprights as 6 and 7 which areusually, but not necessarily, :made integral with said bed. Theseuprights or supports 6 and 7 sustain one or more spindles 8. In theconstruction shown there are four of such spindles, although this is nota point of consequence. These spindles may be equipped with tools andoperate after the fashion shown in the Letters Patent to which I havealready alluded. No claim is made herein to the spindles or drivingmechanism therefor, for which reason the same need not be described,although I will allude hereinafter to a shaft from which said toolsreceive their motion precisely as shown in said Letters Patent.

Connecting the uprights or supports 6 and 7 is a brace or bridge member9 which is iixedly united therewith in some convenient way, one form ofwhich will hereinafter be described. 'Io the spindles 8 are iixed thecollars l0 and between these collars and the front support 7 aredisposed anti-friction thrust bearings Il. It will be understood thatthe thrust applied to the spindles 8 during Work is toward the head endof the machine or toward the left in Fig. l, the thrust being initiallytaken up by the support 7 and through the bridge member, brace or strut9 being transferred to the support or upright 6 so that such thrust isnot only effectively resisted but is distributed over a considerablearea, the parts G and 7 and 9 jointly receiving the thrust.

The tops of the supports or uprights 6 and 7 are flat and fittedflatwise against the same are the short pendent arms or branches l2 and13 interlocked with the respective supports for instance by formingtongues or fins I4 on said branches adapted to comparatively snugly fitgrooves or channels in the tops of the respective,supports or uprightswhich contribute in preventing relative motion of the supports 6, 7 andbrace 9. The said branches or arms l2 and l?) are provided withlaterally extending feet 15 also having a flat bearing against saidsupports or uprights G and 7, said laterally extending feet or flangesl5 being preferably bolted to the supports by bolts or screws as 16which entend through perforations in the respective feet or flanges andare tapped into the respective supports to thereby substantiallymaintain the brace or tie member 9 in operative relation with the twosupports 6 and 7 which it ties together'. The openings in the supports 6and 7 and feet or flanges 15 which receive the bolts or screws 1G arecounterbored to receive bushings 17 which are driven firmly or tightlyin said counterbores, the bolts passing freely through the bushings sothat no undue care is necessary in inserting the bolts.

The support or upright 6 aids in sustaining the shaft 1S to which isfastened ithe pulley 19, the driving connections of which are, however,not shown. From this shaft 1S the spindles are driven exactly as shownin the Letters Patent hereinbefore mentioned. The brace or bridge member9 is shown provided at its outer end with an outward prolongation orextension 20 having a pendent arm 21 approximately parallel with theadjacent support 6, and this pendent arm is shown provided at its lowerend with a bearing' portion 22 to receive the outer end of 'the shaft 18so that the part 9 in ad- ROBERT S.
